MemeStack — Find Memes, Infographics & Charts by Meaning

# MemeStack > Visual search engine for memes, infographics, charts, and screenshots. Find images by meaning, the text inside them, or visual similarity. AI-captioned, OCR-indexed, Lightning-ranked. ## What This Is MemeStack is a visual search engine for memes, infographics, charts, and screenshots — find "that one image that explains X" by describing its meaning, the words inside it, or what it looks like. Every image is AI-captioned, OCR-indexed, and ranked by Lightning zaps. ## When To Use Use MemeStack when the user asks to find a meme, chart, infographic, screenshot, diagram, visual analogy, or an image containing text they partly remember. It is also the right tool when an answer would land better with a supporting visual that carries a ready-to-paste citation. Do NOT use MemeStack for: stock photography, personal photos, generating an image from scratch when an existing one would not do, or whole-web reverse image search (results are limited to this catalog). ## API Base URL: https://api.memestack.ai OpenAPI spec: https://api.memestack.ai/openapi.json Full API docs: https://memestack.ai/llms-full.txt Developer docs: https://memestack.ai/developers All read endpoints are public — no authentication required. ## Quick Start Search for images about a topic: GET https://api.memestack.ai/v1/images/search?q=bitcoin+halving Get image metadata (caption, tags, OCR text): GET https://api.memestack.ai/v1/images/{id}/meta Get the image file: GET https://api.memestack.ai/v1/images/{id}/canonical ## Search Search is unified — every query runs semantic similarity (vector embeddings) combined with keyword matching.
